Location Service

Introduction

The Location Service is used to register and find CSW services in the TMT network. A service can be an Akka actor (including CSW components, such as assemblies and HCDs), an HTTP server or a server running on some TCP host and port.

For information on using the Location Service, see these sections:

Location Service Implementation

Core implementation of location service uses

• Akka Cluster
• Conflict Free Replicated Data Types (CRDTs)
• Akka Http.

You can find more details on how CSW is using this in csw-location-server.

The implementation of the Location Service is split into following four sub-modules:

• csw-location-api - common API implemented by the csw-location-server and csw-location-client
• csw-location-server - think of it as a agent which runs on every machine and exposes HTTP routes which underneath uses akka cluster and distributed data.
• csw-location-client - lightweight HTTP client for location service
• csw-location-agent - an application used to register non-csw services (Http/Tcp).
